I think focusing on the pass first is a mistake at Nebraska, and will be Riley's undoing like BC for a couple of reasons
1) it's not the culture here, and the fan base has very little patience for it if you are not winning. Husker fans want to win, so if you are doing that, life is good. But, if you aren't winning while playing a style that doesn't fit the Husker fans' eyes, you have a short leash.
2) weather. You are going to play games it crappy weather in the B1G, that's just part of the deal. If your offense is based on a finesse air game, you will get in trouble
3) recruits. A sustained dynamic passing attack requires many elite players at the skill positions. Those are the players that schools in the Midwest have a tougher time getting on a regular basis. Our natural recruiting area is filled with cornfed bruisers that can move the pile, but not speedsters. Can we get some every now and then? Sure. But, places like Oregon, Clemson, USC, etc. can stock pile 20 of them on their team. If only 5 of those guys work out, they are in great shape. If we only have 5 on our team, we need every single one to pan out.
I really think we need to go the MSU/Stanford route. Through our entire offensive recruiting force around developing a dominant rushing attack. We can do that with Midwest guys. Then, build an efficient passing game around that. Does not need to be dominant.
But, I digress. I do like that Riley has a plan and is sticking to it. I just happen to disagree with the plan.
